Pinterest is an online pin board where you can create themes of content on "boards". It's a great tool for patient education as it's less reliant on daily updates and can be managed with just a few spare minutes each day.
Facebook is a large player in the world of social media and can play an important role in patient education, as it's a familiar venue for most patients. However, Facebook does need daily monitoring, and is a bit riskier in terms of HIPAA compliance and privacy concerns. If you opt to create a Facebook page for your clinic, be sure you go in with a clear strategy of the type of content you'll be posting, and that patients are clear of its purpose so they do not use it as a forum for communicating health concerns.
Direct Mail
Direct mail has long been recognized as an effective tool for re-engaging inactive patients, so it only makes sense that it would be a great tool for checking in, as well. The personal nature of direct mail can go a long way in motivating your patients to stay on track.
